  The present invention relates to a unit structural member of a building using an M-shaped channel made of metal and a floor structure using the unit structural member.

  The applicant has found that the M-shaped channel made of metal is more effective as a load-bearing material for buildings than other shaped channels (steel), and has been researching steel houses using the M-shaped channel as a structural element for many years. Has been repeated. Patent Documents 1 to 7 have been filed as the result.

  Steel houses have high durability, earthquake resistance, and fire resistance, and are promising as so-called two hundred-year houses, and are expected to be realized as building styles that do not depend on wood houses that damage the natural environment.

  There are also advantages such as dismantling and repeated use, or recycling to metal.

There is provided a unit structural member of the building including a plurality of transverse bones formed in parallel with a longitudinal interval of a longitudinal bone.

  The present invention also provides a unit structural member in which oblique bones made of a short material of the M-shaped channel are arranged on a substantially diagonal line of a frame defined by the vertical bone and the horizontal bone.

  The M-shaped channel forming the vertical bone and the M-shaped channel forming the horizontal bone are formed by polymerizing the bottom plates of the left and right U-shaped channel portions, and connecting the vertical bone and the horizontal bone on the overlapping surface. A structural member is formed.

  The unit structural member is used as a floor frame that supports a floor panel or a ceiling panel. The M-shaped channels forming a pair of vertical bones are arranged in parallel in the vertical direction, and are arranged in parallel at intervals on a horizontal plane, and a floor plate is placed on the upper vertical bones of the unit structural members arranged in parallel.
